Would one of those challenges be the relentless onslaught of Chinese clones? Will Saleae be next?
Let's be real here for a second.
The first gen of USBee and Saleaes were *literally* nothing more than an FX2LP devkit with a different USB VID/PID. Literally. You can buy the $3 dev board off any supplier, use their software and there was no difference whatsoever.
That, my friends, isn't someone "stealing your idea" -- that is you being absolutely stupid and in such a rush to get to market you fail to basic, basic IP protection.
I bought a real, honest-to-God USBee SX. The software was shit. The promise of multiplatform never came, and the promise of file formats and plugins never came. I should've bought a Saleae. I remember the internal (as in, in my head) debate over which to buy. I bet on the wrong horse.
Saleae fixed things with their new analyzers. I have one sitting on my desk right beside me. Great hardware and they have *always* had amazing software. They learned their lesson quickly and moved on. Their business prospered. I'm very, very happy for them and will continue to use their products.
USBee didn't die because of the clones. They died because they failed to innovate, failed to deliver on promises made to their customers and ultimately stay relevant in a rapidly evolving market.
